To understand the location of this picture, cf. picture 97 of the same date.
Here, "all of volunteers of the Solomon Islands" can presumably be understood as relating to "Youth Challenge International" (for more info, cf. the note of picture 89). For all of the volunteers (not restricted to those of the Solomon Islands), cf. picture 98.
Original Spanish caption to this photo:
